Born in Madison, Wisconsin, to Indian parents, he spent most of his childhood in Mumbai, India and Sunnyvale, California. In his late teens, he studied at the New York Film Academy's Los Angeles school.
He married his girlfriend of ten years, Avantika Malik, in early 2011. His uncles Aamir Khan and Mansoor Khan and his grandfather, Nasir Hussain, all had careers as movie Directors and producers.
